Lecturer
- Fernando dos Santos Antunes

Prerequisites
Not applicable.

Objectives
1.Know the main actors in altarpiece production and the materials and production techniques of altarpieces and other carved objects;
2.Identify and understand the causes of alteration and deterioration of objects: the alterability processes, the natural aging of materials, and the alteration of materials – damage and pathologies;
3.Understand and apply the theory of conservation and restoration in altarpieces and carving, in the different interventions according to the criteria and deontological, ethical and technical aspects to be taken into account in the design and intervention phases;
4.Understand and carry out the preparatory phase of treatments, applying basic rules of organization and operation in the laboratory and shipyard, carrying out the registration and documentation of the work and intervention process, the identification of materials and techniques of the object, the preparation of diagnosis and formulation of treatment proposal;
5.Understand and perform conservation and restoration treatments at the level of structures and at the level of surface strata.

Evaluation Methodology
Acts of Integrated Evaluation and Their Weighting in the Continuous and Final Evaluation:

THEORETICAL (50%)
-Technical Data + Work Sheet (25%)
-Written work (25%)

LABORATORY PRACTICE (50%)
-Performance (35%)
-Attendance/participation (15%)

Additional information:
-The assessment results from the weighting of the assessment items of the theoretical component (writ
ten works - 50%) and the practical laboratory component (performance and attendance/participation - 50%) with the student having to obtain at least 10 values for each component to get approval;
-The students who have an average equal to or greater than 10 do not need to take the exam;
-Students who obtain at least 10 marks in the laboratory practical component will be admitted to the exam;
-Students who do not obtain at least 10 marks in the laboratory practical component will be excluded from the exam;
-Possible improvements will only be made to the theoretical component (written work) the assessment obtained in the practical laboratory component being considered in the final global weighting.
